Brief summary

The purpose of this study is to test whether a oral micronized progesterone reduces the Vasomotor Symptom Score comprised of the number and severity of hot flushes and night sweats in perimenopausal women. Oral micronized progesterone is molecularly identical to human progesterone, a steroid hormone. It is sold by prescription for use to prevent endometrial cancer in women taking estrogen in menopause. This research study will test whether progesterone reduces perimenopausal hot flushes and night sweats. It will also test whether progesterone improves sleep disturbances and anxiety.

Detailed description

This is a randomized, double-blind placebo-controlled trial of oral micronized progesterone (300 mg daily at bedtime) for perimenopausal women living anywhere in Canada. Using the self-reported maximum menstrual cycle length in the previous year, women will be stratified as in Early Perimenopause (\<60 days) or Late Perimenopause (\>=60 days). The design includes a 28-day baseline run-in followed by 12 weeks of randomized therapy.

Interventions

300 mg as 3-100 mg capsules taken orally at bedtime daily for 12 weeks

DRUGplacebo

placebo comparator, taken as 3 round capsules at bedtime daily for 12 weeks

Inclusion criteria

1. Between 35-58 years of age 2. At least 4 vasomotor symptoms (VMS) per day, on average, for at least 2/4 weeks or at least 56 over a four-week period. In addition, women should report having VMS of moderate or severe rather than mild intensity. Women reporting fewer VMS than this, but who report night sweats that awaken them from sleep on two or more nights per week will also be included. 3. Perimenopausal status either based on irregularity of menstrual periods, or by onset of new perimenopausal symptoms in women with regular periods. 4. At least one menstrual period within 12 months of study enrollment 5. Ability and willingness to complete the Daily Perimenopause Hot Flush Calendar recording instrument. 6. Ability to understand, speak, read and write English. 7. Women who are at high risk for breast cancer (ie first degree relative with breast cancer, known/suspected history of breast cancer) will be required to have a normal mammogram and clinical breast examination within 12 months of study enrollment.

Exclusion criteria

1. VMS without perimenopausal etiology. 2. Women who have had a hysterectomy and/or ovariectomy. 3. Peanut allergy (because peanut oil is used in the progesterone formulation.) 4. Current or recent (within the last 6-mos.) use of hormonal therapies (estrogen, progesterone, hormonal contraceptives, hormonal fertility treatments), or plans to initiate use during the study period. Two exceptions: women using progestin-releasing intrauterine device (IUD) will not be excluded as it is felt that level of hormone released will not have an effect on VMS and women taking very low-dose transdermal progesterone therapies who have VMS and meet inclusion criteria will be considered on a case-by-case basis. If enrolled, women with these exclusion exceptions will be required to continue and document use of these therapies throughout the entire trial. 5. Planned pregnancy or fertility treatment during the study period. 6. Women who are breastfeeding. 7. Participants with a score greater or equal to 15 on the Personal Health Questionnaire (PHQ-9) will be assessed on a case-by-case basis. Women assessed as needing further investigation and/or treatment for depression will be excluded.

The VMS Score will be calculated as follows: Daily VMS Score = (# night sweats) x (severity) + (#hot flushes) x (severity). Outcome is the average daily VMS Score during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate.

Pre-assignment details

Enrollment required meeting eligibility criteria by screening questionnaire but also required eligible hot flushes and night sweats on a 28-day Calendar. The difference between the listed enrolled and those who were randomized represents this fact.
